piechart not drawn correctly about roughviz HOT 5 OPEN

Hi @valendinosaurus,
could you provide your code?

from roughviz.

Hi @jolo-dev

In my service, I create the chart like this

new roughViz.Pie({
	element: element,
	data: data,
	width: width,
	height: height,
	roughness: roughness,
	fillStyle: 'hachure',
	fillWeight: 4,
	innerStrokeWidth: 1,
	simplification: 0.5,
	axisFontSize: '1rem',
	tooltipFontSize: '1rem',
	labelFontSize: '1rem',
	titleFontSize: '1rem',
	axisRoughness: 0.5
});

and my data gets created like following

mapAccountsForRoughViz(accounts: AccountNormalized[]): {} {
	let labels = [];
	let values = [];
	accounts.forEach(a => {
		labels.push(a.name);
		values.push(a.saldo);
	});
	return {labels, values};
}

resulting in this effective data

{
    "labels":
        ["Hauptkonto","Sparkonto"],
    "values":
        [1064.5899999999701,3497.4500000000007]
}

I also tried to round the numbers with Math.round() resulting in

{
    "labels":
        ["Hauptkonto","Sparkonto"],
    "values":
        [1065,3497]
} 

but the result is the same. I have another chart at a different place with more than two elements, there I never saw this behaviour. Funny enough, from time to time the chart with only two elements gets drawin correctly, but I couldn't reproduce the behaviour.

I suspect it has something to do with having only two elements, if I alter my function mapAccountsForRoughViz that it pushes everything twice (resulting in 4 elements), the chart gets drawn correctly.

Oh yes, you're right. With two elements there is "weird" behavior.
I have tested that in the example:

Let me check what I can do.

Hi @jolo-dev, just wondering if you have any updates on this or any suggestions/direction for me to try and resolve it if I can?

Hi @vcheeze,

Sorry, totally forgot about this.
I would love your contribution :)
